Note. — I. — When the sign of the CoiTeetion is + , the quantity is to be added to 

 the observed scale reading, and when — to be subtracted from it, 



II. — Mercurial Thermometers are liable, through age, to read too high ; 

 the Thermometer ought, therefore, at some future date, to be again tested at the 

 melting point of ice, and if its reading at that point be found difierent from 

 the one now given, an appropriate correction should be applied to all the 

 above points.
